Noninvasive Evaluation of Symptomatic Women with Suspected Coronary Artery Disease

Area of Science:

• Cardiology
• Medical Diagnostics

Background:

• Cardiovascular disease (CVD) is a leading cause of death in the US.
• Diagnosing coronary artery disease (CAD) in women presents unique challenges, including atypical symptoms like nausea, dyspnea, and fatigue.
• Women often exhibit nonobstructive CAD, microvascular dysfunction, and other abnormalities impacting diagnostic accuracy.

Purpose of the Study:

• To provide an overview of diagnostic modalities for symptomatic women with suspected CAD.
• To examine the effectiveness of various tests in diagnosing and managing CAD in this population.

Main Methods:

• Review of current guidelines for initial testing in symptomatic women.
• Evaluation of exercise electrocardiography (ex-ECG) and its limitations in women.
• Assessment of other diagnostic modalities including echocardiography and SPECT imaging.

Main Results:

• Exercise electrocardiography (ex-ECG) has a lower positive predictive value in women compared to men.
• Atypical symptoms in women complicate early risk assessment for CAD.
• Nonobstructive CAD and microvascular dysfunction can reduce the accuracy of noninvasive tests.

Conclusions:

• Accurate diagnosis of CAD in women requires careful consideration of symptoms and test limitations.
• Further research into effective diagnostic strategies for women with suspected CAD is warranted.
• Multimodality approaches may be necessary for comprehensive CAD evaluation in women.
